A ventilation system in which an organism moves gas-containing media in and out of an internal gas-exchange organ such as a lung would be considered:

Assume the maximum output levels of the comparator in the figure above are ± 14 V. Also R1 = 15 kΩ, R2 = 30 kΩ. When the input value is 4 V, the output value is __________V. (The unit of the answer is [V]. Do NOT type the unit when you type your answer) (If the answer is negative, include the negative sign “-” when you type your answer)

A sine signal Vin with an amplitude of 8 V is applied to the comparator in the figure above. Also R1 = {R1} kΩ, R2 = {R2} kΩ. The reference voltage set by R1 and R2 is __________V. (The unit of the answer is [V]. Do NOT type the unit when you type your answer)

VIN1 = 1 V,   VIN2 = 2 V,   VIN3 = 3 V,   VIN4 = 4 V,   R1 = {R} kΩ,   R2 = {R} kΩ,   R3 = {R} kΩ,   R4 = {R} kΩ.   Specify the value of Rf required in the averaging amplifier in the figure above. (The unit of the answer is [kΩ]. Do NOT type the unit when you type your answer)
